<p>An electronic device is formed of circuit boards supported on a device rack (1000), of which circuit boards the parallel first and second one are at a certain distance from each other, measured at right angles to the surface of the first and second circuit board. The first edge of the circuit boards is arranged to be supported by the first level surface (501, 1001) of the rack, and the second edge parallel with the first edge of the circuit boards is arranged to be supported by the second level surface (1002) of the rack. For supporting the first edge of the circuit boards, the first level surface of the rack comprises outward protruding embossments (502), which are of the same material as the level surface. Between the point arranged to support the first edge of the first circuit board and the point arranged to support the first edge of the second circuit board there is a first embossment (502), the extent of which at right angles to the surface of the circuit boards is the same as said distance between the circuit boards, and which has two parallel edges, the direction of which differs substantially from the direction intended as the direction of the first edge of the circuit boards.</p> |
